Let's get more breaking news. Josh is here. Out of syria. Breaking. And our terry moran is in the middle of it all, inside the war zone, telling us about the massive bomb that struck a crowded and densely-populated neighborhood in the capital of damascus, not far from a busy mosque and a school. Several children are among the dozens of people killed in the attack. And terry joins us, now, from a location not far from the bomb site. Good morning to you, terry. Reporter: Josh, this was just a huge explosion. Some kind of carbomb devastating these apartment buildings. Blasting the road to shreds. And we're told there was a school behind where the bomb exploded. Many of the dead were children coming in or out of that school. This has become a regular occurrence in damascus now. The giant carbombs, one of the biggest we have heard of. We believe we heard other explosions. This is a city where the war is closing in. In some ways, damascus is becoming more like baghdad. We hear from the residents, the point of this is to terrorize them, to get them to come to their knees. But the spirit in the face of something like this is defiance. Another day of death in damascus. Josh? Terry, thank you. And please, be safe. Terry will bring us reports throughout the morning as developments warrant. He'll have reports on tonight's "world news" and later on "nightline."
